Study on adsorptional state of some Schiff bases on silver sol

Four Schiff base compounds N-2-chlorobenzaldehyde-L-alanine(abbr.2-CAK),N-4-chlorobenzaldehyde-L-alanine(abbr.4-CAK),N-2,4-dihydroxylobenzaldehyde-D-glucosamine(abbr.DG)and N-salicyladehyde-D-glucosamine(abbr.SG)were synthesized and studied with surface-enhanced Raman spectroscopy and Fluorier-translated Raman spectroscopy.The assignments of all compounds'Raman spectrum have been determined.The adsorbed states that on silver colloid of four Schiff base compounds were determined.It was found that 2-CAK and 4-CAK are adsorbed on the Ag surface through the carboxyl oxygen atoms and adopt upright conformation,that DG and SG are adsorbed through the hydroxyl oxygen atoms of sugar ring and phenol.The adsorbed state of the Schiff base shows chemical adsorbed feature.
